I use tomato paste quite a bit when making tomato sauces. But I hear from various people refer to tomato paste as if it's a shortcut or cheating. A friend of mine is so proud of her tomato sauce and follows it up by saying "and I never have to use paste." Someone else recently said that tomato paste was the secret ingredient to her sauce but not to tell anybody. Sometimes even my husband asks me why I'm putting tomato paste in my sauce. What's the big deal then?
